PRINTING-TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 397,466, dated February5, 18819. Applieationfiled October 1'7, 1387. $erial No. 252,641. (Nomodel.)

To all whom it may concern:

Be it known that I, ANDREW T. 310003;, a subject of the Queen of GreatBritain, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement inPrintingTelegraphs, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to the 1n'inting-machine of a printing-telegraph;and it consists in such a machine embodying three typewheels, and in thedevices and their combinations for adj usting the type wheel or wheelswith reference to the platen or press-roller and strip of paperto beprinted, substantially as hereinafter set forth, and specificallypointed out in the claims.

In the drawings, Figure 1 is a front view of so much of an electricprinting-machine embodying my improvements as is sufficient forillustration of my invention. Fi 2 is a side view of the same.

I prefer to use three type-wheels, A, B, and C. These wheels are joinedtogether as one piece and are on a shaft, a, which has bearings b in theframe of the machine. The wheels may slide lengthwise on, but revolvewith, the shaft, there being a spline, c, fixed to the shaft, but loosein the hubs of the wheels. The shaft (6 may be revolved by means ofagear, R, driven by clock-work or other well-known motive mechanismsuitable for this class of machines, and which it is not necessary todescribe herein. Radiating from the shaft a is a pin, (1, here shown asprojecting from a flange, e, which may be adjusted and fixed on theshaft. livoted at f is the ordinary press-lever, D, bearing an armature,E, to be operated by the press-magnet in the usual manner. The outer endof this lever bears the platen or press-roller F. Pivoted on the side ofthe press-lever, or at g, to a stand, h, fixed thereon, is a lever, G.The outer end of this lever is turned up so as to meet the pin (i whenthe latter is immediately over the same, as shown. The normal positionof the lever G is, as shown, the inner end-which is supposed to be theheavier end-having a pin, i, which rests on a projection j, on the stand71,. From the inner end of the lever G projects another pin, is, whichmay meet an arm, .ll, pivoted to the frame of the machine at Z.

On a rod, 1, which may slide endwise in bearings m in the frame, are twoarms, a, which meet the type-wheels in such a manner that the latter maybe moved endwise thereby. 011 the rod I is another arm, J, on which is aprojection or pin, 0, and the lower end of which has a slot, p.

A threearmed piece, K, is pivoted at q to the frame or to a stand, L,fixed thereon. The piece K may swing to bring the upper end of the arm2' into position on either side of the arm H, as required, the arm Hserving as a locking-piece. The limit of the motion of the piece K ineither direction is determined by pins 8, fixed to the stand L, each ofthese pins being met by one or the other of the two armst and u of thepiece K. The pins .9 also serve as stops for the arm J. The piece K isformed to present two stops, c and at, one or the other of which is metby the projection or pin 0.

Located in suitable position is a permanent magnet, a part of each ofthe poles LT and S of which is shown. An armature, M, bearing a helix,is located between the poles of this magnet on a shaft, 0, which hasbearings at y and is provided with an arm, P. The outer end of this armhas a stud, which enters the slot 13 in the arm J.

It is not necessary to herein describe the mechanism for operating thepress-lever, or for securing unison of movement of printingmachine andtransmitter. For present purposes this may be supposed to be such as iswell known. The pin (Z is to be set at the zero or unison point, withreference to each of the type-wheels, and also with reference to thecorresponding device of the transmitter.

The object of my invention, in general, is to move a type-wheel endwisethat is, in a direction transverse to the strip of paper to beprinted-and in. particular, when three type-wheels are used, to thusmove them so that the central wheel, B, may be brought over either halfof said strip; or, in other words, over either the right or left handportion of the platen or press roller F; or the IOO right-hand wheel, C,over the right-hand portion of the rollerF, or the left-hand wheel, A,over the left-hand portion of said roller.

On each upward movement of the presslever l) the lever G, pivotedthereto, will be carried upward, but not so as to touch the arm H,provided that the pin (Z is not in position directly over the outer endof the lever G. In case that the pin (Z is over the end of the lever G,the arm .II will be swung upward by the lever G above the end of the arm0.

If no current passes through the helix of the armature l\l,t-here willbe no movement of the type-wheels endwise. If, however, (the armature Mand other parts of the mechanism being in the positions shown,) acu'rrei'lt be sent through. this helix tending to move the armature soas to swing the arm I to the right, then the red I will he slid by thearm J and the type-wheels moved by the arms n to the right, so as tobring the wheel A over the pressaroller and strip thereon. At any time,except when the lever G is swung by the pin (1, the wheel 13 may bebrought back into its former position upon a reverse current passingthrough the helix, when the arm P will be swung back until the pin 0meets the stop 1'; butthe parts being in the positions shown in thedrawings i-l a current be sent through this helixtending to move thearmature to swing the arm P to the left, when the pin (1 meets the leverG, then the piece K- being free to swing, since the armll is carriedabove, so as to release the arm. o'will be swung, the pin 0 pressingagainst the stop 1: to that end. Thereupon the pin 0 will pass underthis stop, and hence, by means of the devices between the armature illand the type-wheels, the latter will be moved so that the wheel 0 will.be brought over the pressroller and strip thereon. \Vhile the piece K isheld in the last-specified position the wheel B may be brought over theleft-hand portion of the press-roller, or the wheel C be brought backover the press-roller, at will, according to the nature of the currentsent through the helix. Thus, without further explal'iation, it will beunderstood that if the electrodes connected with the helix of thearmature M extend to the transmitting-station the operator thereat maycause, by sending a current of the proper sense and at the proper timewith reference to the movement of the unison mechanism at each station,either type-wheel to take the position (with reference to the strip tobe printed) desired and above specitied.

IVhile my invention, so far as relates to aehange of location oftype-wheel with reference to the strip to be printed, is applicable whenany number of type-wheelsis emphuyed, yet it is of my invention toembody in the machine three type-wheels located with reference to eachother as above specified and adapted for the purposes hereinafter named.

The machine is of the class of machines commonly called tickersjl andwhich are.

generally used for stock-reporting. The printing is done on a strip ofpaper, and there are two parallellines of printed matter. I so apportionon the wheels the type for the characters to be printed that each of theouter wheels, A and (I, bears the type required for only one of saidparallel lines, while the mid dle wheel, 13, has type to be used foreither of said lines. Thus, for instance, the wheel A may have lettersand such. as are only needed for printing on the left-hand part of thestrip, the wheel (I such figures as are used only for the right-handpart of the strip, while the wheel B may have certain characters,letters, and figures that are required for both parts of the strip orlines of printing. The result of such arrangement is that the leastchange or shifting of the type-wheels is required, and hence a greatsaving of time and the most expeditious transmission of messages.

Uertain modifications might be made in the construction of the machinewithout altering prominent features of the invention-modifications whichwould occur to any mechanic skilled in the art, and which need not beillustrated herein, being such as would arise in the adaptation of theinvention to the various machines dilii'ering in form and mechanism forrotation of the type-wheel.
